Solana (SOL) Hits 30 Months of 100% Uptime, Cementing Resilience
Solana (SOL) has reached a milestone few blockchains can claim: 30 consecutive months of uninterrupted network uptime. Since February 2024, the network has avoided any full-cluster outages, demonstrating its resilience amid surging transaction volumes and infrastructure challenges.
The achievement is significant given Solana’s early struggles with reliability. Between its 2020 launch and early 2024, the network endured multiple outages, including a 17-hour halt in September 2021 due to transaction flooding and a nearly five-hour incident in February 2024 tied to validator issues. However, since that last major disruption, Solana has operated seamlessly, even as it processes more daily transactions than all other major blockchains combined, according to Chainspect.
Battle-Testing the Network
Solana’s resilience was recently put to the test on August 12, 2026, when a routing failure at its largest infrastructure provider, TeraSwitch, knocked 29% of the network’s stake offline. Despite this, the blockchain continued producing blocks and processing transactions without interruption. The incident highlighted the network’s redundancy, a result of preemptive efforts to reduce stake concentration at TeraSwitch from 38% to below 30% over the past year.
Such challenges have shaped Solana’s approach. Lessons from past outages have led to improvements, including stake-weighted quality of service (SWQoS) to manage transaction traffic and a redesigned transaction scheduler to prevent duplicate transactions. These incremental upgrades have fortified Solana’s ability to handle stress without halting operations.
Reliability Backed by Data
Institutional users often evaluate reliability in terms of uptime percentages, or "nines." While major providers like AWS and GitHub aim for 99.99% and 99.9% uptime, respectively, Solana has achieved 100% uptime since February 2024. This is particularly notable given the blockchain’s high activity levels, including record-breaking single-day transaction volumes and over $4.7 trillion in stablecoin transfers in the past year.
For context, Solana’s native token, SOL, is trading at $102.03 as of September 14, 2026, up 1.71% in the last 24 hours. The network’s reliability, combined with its scalability, continues to attract enterprises like Western Union, Franklin Templeton, and MoneyGram, which have integrated Solana for financial applications.
Looking Ahead
Solana’s engineers are leveraging this reliability to push the network’s technical limits. Recent upgrades include reducing slot times to 300 milliseconds, with a goal of hitting 200 milliseconds, and cutting storage costs by 90%. The upcoming Alpenglow upgrade, expected later this year, aims to reduce finality to 150 milliseconds. Meanwhile, the network recently sustained a record 5,000 user transactions per second, showcasing its growing capacity.
With its strong track record and continuous innovation, Solana is positioning itself as a cornerstone of blockchain infrastructure. As the network continues to scale and improve, its ability to maintain 100% uptime will remain a critical selling point for institutional adoption and long-term investor confidence.
